Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
Do you have the door panel off by any chance to do voltage tests at the window motor?
Well the power reverses at the window motor for up and down. We need to check with a volt meter to see if the window motor is getting power and ground going down and if the power reverse going up. If it does, then you have a bad window motor.
Do you have a volt meter?
You don't adjust voltage. It should be around battery voltage when you apply power to it. So example. If you have the key in the ON position, and you put the volt meter on the window motor and you push the switch down and you see 11.2 volts while back probing the window motor with a positive and negative lead. That is good. If you then push the switch up and the voltage changes to -11.2 that means the window motor has to be the problem.
If you have the correct voltage at the window motor, it has to be a window motor. If you don't have the correct voltage, then maybe a wiring issue.
